Abstract
The utility model discloses a focal position adjustable Fresnel lens system which can be used to effectively change the focal position of a Fresnel lens after condensation so as to satisfy the requirement that a Fresnel lens is used in condensation in the engineering and various requirements on the focal position. A concave mirror is arranged behind the Fresnel lens and the focal point thereof, due to the reflection and condensation of the concave mirror, the light direction of the Fresnel lens after condensation is changed to make the focal position of the Fresnel lens after condensation is changed. When the position and the angle of the concave mirror are changed, the focal position is also changed correspondingly, so the engineering needs in different occasions can be satisfied. The focal point of an existing Fresnel lens is fixed and unchanged, inconvenience is brought for some occasions or even problems of low efficiency and waste can be caused; according to the utility model, the problems can be solved, and the solar energy development and utilization effect can be effectively improved.
Description
The application's request: application number 201310228640.3, on June 9 2013 applying date, denomination of invention is the right of priority of the application for a patent for invention of the adjustable Fresnel Lenses system in focal position.
Technical field
The utility model relates to the adjustable Fresnel Lenses system in a kind of focal position, can change the focal position after Fresnel Lenses optically focused, to meet the requirement that uses Fresnel Lenses optically focused and focusing position in engineering.
Background technology
Fresnel Lenses is widely used in photovoltaic, photo-thermal system, but the focus of existing Fresnel Lenses is changeless, this makes troubles and even causes inefficiency or waste to some application scenario, has affected the effective exploitation of sun power and has made full use of.Develop the adjustable Fresnel Lenses system in a kind of focal position to solve problems, to meet various engineering practice needs for this reason.
Utility model content
The purpose of this utility model is that the focus for solving existing existing Fresnel Lenses immobilizes, and makes troubles to some application scenario and even causes inefficiency or waste, and impact is to the effective exploitation of sun power and the problem making full use of.
The utility model relates to the adjustable Fresnel Lenses system in a kind of focal position, can change the focal position after Fresnel Lenses optically focused, to meet the various requirement that uses Fresnel Lenses optically focused and focusing position in engineering.
Between Fresnel Lenses and its focus, concave mirror is set, due to the reflecting condensation of concave mirror, change the radiation direction after Fresnel Lenses optically focused, focal position after Fresnel Lenses optically focused is changed, change position and the angle of concave mirror, focal position is corresponding change also, to meet the requirement of engineering of different occasions.
The beneficial effects of the utility model are:
Can change or regulate the focal position after Fresnel Lenses optically focused, to meet the various requirement that uses Fresnel Lenses optically focused and focusing position in engineering, effectively improve the development and utilization effect to sun power.
